This is a Ruby binding for the Blurhash library. With it you can encode an image as a small string that can be saved in the database, returned in API responses, and displayed as a blurred preview before the real image loads.
Blurhash is written by Dag Ågren.
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:
$ gem install blurhash
To generate the blurhash string from an image file, you need to read in the image pixel data yourself, for example with RMagick:
require 'blurhash' require 'rmagick' image = Magick::ImageList.new('foo.png') puts .(image.columns, image.rows, image.export_pixels)
After checking out the repo, run
bin/setup to install dependencies. Then, run
rake spec to run the tests. You can also run
bin/console for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run
bundle exec rake install. To release a new version, update the version number in
version.rb, and then run
bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the
.gem file to rubygems.org.
